I mean, TES VI could be a rickroll mp4 and still sell millions of copies. There’s a megaton of nostalgia, and gamers are demonstrably… not the smartest shoppers, in aggregate.
Starfield and FO76 are commercial failures, either. Well, not particularly catastrophic ones like others, anyway.
Point being, BGS is not short on time. I posit they have at least one “freebie” no matter what, or maybe a few more mediocre releases that will still sell big.
